CVE-2026-46012 Details
Description
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix memory leaks in rxkad_verify_response() Fix rxkad_verify_response() to free the ticket and the server key under all circumstances by initialising the ticket pointer to NULL and then making all paths through the function after the first allocation has been done go through a single common epilogue that just releases everything - where all the releases skip on a NULL pointer.
A memory leak vulnerability has been addressed in the Linux kernel's Rxrpc implementation, specifically within the Rxkad response verification function. The issue arose because the function did not properly free allocated memory for tickets and server keys under all circumstances. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been fixed.
